First Class

You leave the auditorium and head to your new classroom. You aren't sure what the original classroom was for, it looked sort of like a home ec room, but now it was yours. By the time you enter a few of the girls in the first class were standing around looking on with a mix of boredom and nervous energy. You let them in the room to find seats as you make sure the class is set up correctly. Given that you were only responsible for the 18 or older students you were not expecting large class sizes, around 10 to 15 girls per class period. The room had about that many desks which was fine, though you weren't likely to need them. in the middle of the room the janitors had managed to bring in the queen-sized mattress that your class required. At the moment, it was nothing special, literally a bare mattress on the floor. You'd have to get some sheets for it sooner or later, but for now it would serve the class requirements.

A second bell sounded and the last few students wandered into the room and found seats.

"Good morning class," you greeted. A few girls responded back. "Welcome to your first day of sex ed. Some things to note before we start, this class won't need a seating chart since you'll likely be out of your desks often enough, so I will be taking roll by calling your names. While I'm doing that you can get settled into the first rule of the class, as soon as you enter the room I expect you girls to remove all your clothing and put them in the basket under your desks."

This got the girls talking with a few mild protests about the rule but you quieted them down with a raised hand.

"Listen, I get that you'll all feel a little nervous being naked around each other but it's simply something you'll have to get over. The clothes will just get in the way during class time. Obviously, for health reasons, we can not have you wander the halls nude, but in this room you are to be without shame. When it comes to sex you are going to be showing a lot of yourself to whoever you are with so I expect the same here. Now get undressed while I call roll."

The girls slowly started to do as you said as you ran down the list of names. It took only a minute or so and your eyes took in the feast in front of them. 12 students this class period, and you got to see them bare it all. There was a lot to look at, from the smoke show blonde with massive tits and wide hips, or the rail-thin tomboy-looking girl who was flat but toned to the point you could clearly see her abs. There was the ginger girl sitting right up front, her pale skin making her freckles stand out even more as they covered her whole body. You smiled as you lightly rubbed your cock through your pants.

"Fantastic girls, good to see you getting into the class. Now more personal introductions. I'm Mr. Doe as you now all know. I'll be your guiding light when it comes to sex. Now the second rule of this class is that you must be 100% honest with me at all times. Sex only works if you are totally honest with your partners. Even if the questions feel awkward. On that note with a quick show of hands who in here is still a virgin?" The girls all started to look around and shift in their seats as a few hands went up quickly. "Come now, don't be shy, given that this is an all-girls school I assume the answer is most of you."

You were right of course, as the girls became more honest, hands continued to go up. By the end only two girls kept their hands down, their turn to now feel embarrassed.

"Now," you continued. "The final rule to keep in mind is that when I'm giving you instructions, I expect you to follow them completely and without question. Once you've completed your sexual education class you'll hopefully have the confidence to make demands or negotiate in the bedroom, but until that happens, it is best that you listen to me at all times. Even if you find it gross or scary just trust me, you'll never know what you might like until you've had the chance to try it. With that said the first instruction I'm going to give you girls is to keep your eyes on me as I get ready for class."

As you finished saying that you slowly started to pull off your own clothes. This started the class whispering again but you just ignored them. Tossing your shirt and pants aside you gave the class a slight smirk before pulling down your underwear, standing nude in front of the whole class. Many of the girls started to look away or gasp before remembering your rules and turning back to face your now nude form. Grabbing your hard cock you shake it up and down slightly.

"Look at it girls, the first cock most of you have ever seen, the cock that is going to pop your cherries and for some of you give you your first babies. All of you will have every inch of this cock memorized by the end of the year. This is why you are here, to learn how to make this cock feel good. With all that said, it's time to start our first class."

Letting your cock go you walk over to the mattress on the floor. As you do so you point at the blonde girl with the huge tits. Shockingly, she was one of the first girls to raise her hand and say she was a virgin.

"Angelica, was it?" The girl nodded. "Good come over here, you're going to be today's first participant in sexual education."

Slowly she stood and walked to where you were standing. Gently you pushed on her shoulders just so and she reluctantly laid down on the mattress. Looking around you saw the girls all staring, mildly interested.

"Here's how class will go," you tell them as you rub your cock up and down Angelica's teen snatch. "I will pick a student or more and have them join me on the mattress as I introduce a new concept or just act as a review or practice lesson. As we fuck I expect everyone else to watch and take notes. Once I've cum I'll have a few students whose job it will be to help get me hard again and I will repeat the lesson with a different student. You are free to volunteer for a lesson if you wish but I will pick students who haven't gone before if the same people start to volunteer. Because this is lesson 1 and it is Angelica's first time we'll keep things simple. This will be basic missionary position."

With that you line the head of your cock on the now moist slit of the teen girl under you and slide in. A noticeable barrier meets the head of you cock. Pulling back slightly you turn to the class.

"As stated earlier she's a virgin, and thus still has her hymen. That will have to be broken to proceed. It might hurt a bit Angelica, so try to bear with me."

With that you push back in, harder this time, thrusting right through her virginity and pop it without mercy. She lets out a loud keening whine before you bottom out.

"And with that she is no longer a virgin. Congratulations on that." You tell her as you pull back and push in again. "She is quiet tight-ugh-so it is a bit of work to get in and out again. Remember the tighter the better, so as I push in I want each of you to focus on clenching your pussy as much as you can. Try it now, Angelica."

The girl did as you asked, her face somewhat dazed at the sudden instructions. Her already vice-like cunt managed to squeeze even a little bit extra on your next trust and you rewarded the girl with a quick kiss, before you traveled down her neck with your kissing. The blonde was moaning noticeably now as you worked her over. You leaned back up to address the class.

"Now-ah-the benefits of this po-position is that it allows me access to her tits-Don't forget to tighten on every thrust girl, yes like that-which are fun to suck on or play with," you spend a few seconds demonstrating that as you suck both of her nipples to hardness before using a free hand to tweak them, smirking at the gasp it draws from the girl under you. "Now Angelica tell the class what you are feeling."

"It's big," she gasps out. "And I feel stretched out th-there and ohh it's feeling good but al-so sore."

"Good, very good," you tell her before looking back at the class. "I can feel my climax approaching so please everyone, make sure you pay very close attention."

The students who have been watching red-faced before now start to crowd in a bit more as you speed up your thrusting. Angelica's moans become squeels before becoming shrieks before you thrust as deep as you can one last time and pump a heavy load of cum right into her waiting womb. You grind your hips into her's as you seek out any extra depths you can plunder from the girl before your orgasm finishes. Groaning as you pull out you sit on the edge of the mattress, the blonde teen next you left panting and leaking cum.

"Great job Angelica," you tell her before slapping her thigh lightly. "Now get a few tissues from the counter to keep my cum from dripping all over the floor and return to your seat. You two," you point at a short black haired girl with heavy tits and a small Asian girl. "Come over here, I'll walk you through getting me hard again and I'll pick another student so we can review the lesson."

The two girls walk over and you get them to kneel next to you as you talk them through sucking and licking your tired cock hard again. As they do so you scan for your next teaching partner.
